Dibasic esters (diesters) and their use in plasticizer compositions are generally disclosed. In some embodiments, the diesters are branched-chain esters of long-chain alkanedioic acids, such as octadecanedioic acid. In some embodiments, such plasticizer compositions are used to increase the plasticity of a polymer resin, such as a vinyl chloride resin or poly vinyl butyral. In some other embodiments, such plasticizer compositions are used to lower the glass transition temperature of a polymer resin. In some embodiments, at least a portion of the plasticizer is derived from a renewable source, such as a natural oil.
二元酯(双酯)及其在增塑剂组合物中的使用通常是公开的。在某些实施例中,这些双酯是长链二羧酸的支链酯,如十八烷二羧酸。在某些实施例中,这种增塑剂组合物用于增加聚合物树脂的可塑性,如氯乙烯树脂或聚酮醇树脂。在另一些实施例中,这种增塑剂组合物用于降低聚合物树脂的玻璃化转变温度。在某些实施例中,至少部分增塑剂是来自可再生来源,如天然油。
